Understanding Alzheimer’s and Dementia: What Families Need to Know

Understanding Alzheimer’s & Dementia: A Guide for Families

At All Heart Home Care, we understand that a diagnosis of Alzheimer’s or dementia doesn’t just impact the person living with the disease—it touches everyone who loves and cares for them. This guide is designed for San Diego families. Whether you’re just starting to notice signs or deep into the caregiving journey, we’re here to help you understand what’s happening and how you can best support your loved one.


What Is the Difference Between Alzheimer’s and Dementia?

Dementia is an umbrella term that describes a set of symptoms related to changes in memory, thinking, and reasoning. Alzheimer’s disease is the most common type of dementia, accounting for 60% to 80% of cases. While many people use the terms interchangeably, Alzheimer’s is a specific brain disease that progresses over time.

In Alzheimer’s, nerve cells in the brain are damaged by two abnormal structures: plaques (clusters of a protein called beta-amyloid) and tangles (twisted strands of a protein called tau). These structures disrupt communication between brain cells and eventually cause them to die.


The Numbers Behind Alzheimer’s Disease

Alzheimer’s is a growing public health crisis in the United States. According to the Alzheimer’s Association’s 2025 Facts and Figures report:

  • An estimated 7.2 million Americans age 65 and older are living with Alzheimer’s dementia—about 1 in 9 people in this age group
  • Almost two-thirds of Americans with Alzheimer’s are women
  • Older Black Americans are about twice as likely to have Alzheimer’s or other dementias as older White Americans, and older Hispanics are about one and a half times as likely
  • About 200,000 Americans under age 65 have younger-onset Alzheimer’s
  • Health and long-term care costs are projected to reach $384 billion in 2025
  • Nearly 12 million family members and other unpaid caregivers provide an estimated 19 billion hours of care annually
  • This number could grow to 13.8 million by 2060 without medical breakthroughs

Between 2000 and 2022, deaths from Alzheimer’s disease increased by more than 142%, while deaths from stroke and heart disease decreased.


Understanding the Brain Changes in Alzheimer’s

The human brain is made up of billions of neurons that form networks responsible for everything we do. Alzheimer’s starts in the cerebrum, the largest part of the brain, which controls thought, memory, and language. Over time, neuronal death leads to brain shrinkage, impairing essential functions.

Key symptoms of this damage include:

  • Memory loss
  • Difficulty solving problems or making plans
  • Language struggles
  • Personality and behavioral changes
  • Loss of physical abilities in later stages

Who Is Most at Risk?

Some risk factors can’t be changed, while others are influenced by lifestyle:

Non-modifiable risk factors:

  • Age: Risk increases dramatically with age—5% of people ages 65-74, 13.2% of those 75-84, and 33.4% of those 85 and older have Alzheimer’s dementia
  • Family history and genetics: The APOE-e4 gene has the strongest impact on risk of late-onset Alzheimer’s
  • Ethnicity: Hispanic and Black populations are at higher risk
  • Sex: Women are more likely to be affected, partially due to longer life expectancy

Modifiable risk factors:

The 2024 Lancet Commission on Dementia Prevention identified 14 modifiable risk factors that, if fully addressed, could prevent or delay nearly 45% of dementia cases worldwide. These factors vary by life stage:

Early life (under 18): Low educational attainment

Midlife (45-65): Hearing loss, high LDL cholesterol, depression, traumatic brain injury, physical inactivity, diabetes, excessive alcohol use, hypertension, obesity

Later life (65+): Smoking, social isolation, air pollution, untreated vision loss

The good news: Managing heart health—avoiding smoking, controlling blood pressure and cholesterol, staying active, and eating well—can significantly reduce the risk of cognitive decline.


The Stages of Alzheimer’s Disease

Alzheimer’s progresses gradually and uniquely for each person, but it generally follows three main stages. In 2024, revised diagnostic criteria were published that incorporate advances in biomarker testing to provide objective data for staging disease progression.

Early Stage (Mild):

  • Subtle memory lapses
  • Difficulty finding words
  • Trouble remembering names or recent events
  • Losing items or getting lost in familiar places

Middle Stage (Moderate):

  • Increasing confusion
  • Needing help with daily activities (like choosing clothes or bathing)
  • Changes in sleep and mood
  • Greater risk of wandering
  • Personality changes, including suspicion or delusions

Late Stage (Severe):

  • Loss of awareness of surroundings
  • Difficulty speaking or swallowing
  • Full-time assistance needed for personal care
  • Increased vulnerability to infections

Advances in Diagnosis

Traditionally, diagnosing Alzheimer’s required referrals to specialists and expensive PET brain scans or lumbar punctures. Now, breakthrough blood tests are making early diagnosis more accessible:

First FDA-cleared blood test (May 2025) — The Lumipulse pTau217/Beta-Amyloid 42 Ratio test measures key biomarkers through a simple blood draw, matching PET scan results more than 90% of the time.

Primary care blood test (October 2025) — The Elecsys pTau181 test became the first blood-based biomarker test cleared for use in primary care settings specifically to rule out Alzheimer’s-related amyloid pathology, with a 97.9% negative predictive value.

What this means for patients — Blood tests are quicker and far cheaper than brain imaging, reducing wait times and cost barriers to diagnosis. According to the 2025 Facts and Figures report, nearly 4 in 5 Americans would want to know if they had Alzheimer’s before symptoms interfered with their lives.

If you notice cognitive changes in yourself or a loved one, talk to your doctor about whether biomarker testing might be appropriate.


Treatment and Care Options

There is currently no cure for Alzheimer’s disease. However, 2023-2024 brought historic advances with the first FDA-approved treatments that address the disease’s underlying biology—not just its symptoms.

Disease-Modifying Treatments (for Early-Stage Alzheimer’s):

Two anti-amyloid monoclonal antibody therapies have received full FDA approval for people with mild cognitive impairment (MCI) or mild Alzheimer’s dementia with confirmed amyloid plaques:

Lecanemab (Leqembi) — Received full FDA approval in July 2023. Given as an IV infusion every two weeks, it slowed cognitive decline by 27% compared to placebo in clinical trials. In January 2025, the FDA approved a less-frequent maintenance dosing option (every four weeks) and a weekly subcutaneous self-injection for at-home use following the initial treatment period.

Donanemab (Kisunla) — Approved in July 2024. When administered monthly via IV infusion, clinical trials showed a 35% reduction in the risk of disease progression. Uniquely, treatment may be stopped once brain scans show amyloid plaques are sufficiently reduced.

Important considerations: These treatments are only approved for early-stage Alzheimer’s with biomarker-confirmed amyloid. Both carry a risk of ARIA (amyloid-related imaging abnormalities)—brain swelling or micro-bleeds detected through MRI monitoring—which is more common in people with the ApoE4 gene variant. Medicare covers medications after traditional FDA approval.

Symptom-Managing Medications:

For people at any stage of Alzheimer’s, these medications may help manage symptoms temporarily but do not stop disease progression:

  • Cholinesterase inhibitors: Donepezil (Aricept), Rivastigmine (Exelon), Galantamine (Razadyne)
  • NMDA receptor antagonist: Memantine (Namenda)
  • Combination therapy: Donepezil + Memantine (Namzaric)

Non-Drug Approaches:

Non-medication strategies are powerful tools in caring for someone with dementia:

Redirect instead of correct — Meet the person where they are, rather than arguing with their reality.

Create a calm, familiar environment — Reduce confusion by maintaining consistent routines and surroundings.

Look for sources of discomfort — Behavioral changes may signal pain, hunger, cold, or other unmet needs.

Encourage meaningful activity and rest — Music, art, gardening, and gentle exercise can improve quality of life.


Reducing Your Risk

Research continues to demonstrate that healthy lifestyle interventions can help protect cognitive function. The Alzheimer’s Association U.S. POINTER trial—a two-year multidomain lifestyle intervention—showed improved cognition in older adults at risk of cognitive decline.

Steps you can take to promote brain health:

Stay physically active — Regular exercise is one of the most effective ways to reduce dementia risk.

Protect your hearing and vision — Address hearing and vision loss early; the ACHIEVE trial found hearing aids reduced cognitive decline by 48% over three years in high-risk adults.

Manage cardiovascular health — Control blood pressure, cholesterol, and blood sugar.

Stay socially connected — Maintain relationships and engage with your community.

Keep learning — Challenge your brain with new activities and continued education.

Limit alcohol and don’t smoke — Both are linked to increased dementia risk.

Get quality sleep — Poor sleep is associated with increased risk of cognitive decline.


Advancing Research and Hope for the Future

Alzheimer’s research has shown that brain changes begin years—even decades—before symptoms appear. Scientists are working to detect these early changes and intervene sooner. The Alzheimer’s Association invested $112.2 million in research in 2025, the largest single-year investment in its history, bringing total active investments to more than $450 million across 1,200+ projects in 56 countries.

Clinical trials offer hope and opportunities for individuals living with Alzheimer’s and their families. You can learn more or search for studies through:


Support for Caregivers

Caring for someone with Alzheimer’s or dementia is one of the most challenging roles a person can take on. In 2024, nearly 12 million caregivers provided more than 19 billion hours of unpaid care valued at $413 billion. More than half of caregivers rate their emotional stress as high or very high.

New Federal Support Through the GUIDE Model:

The CMS Guiding an Improved Dementia Experience (GUIDE) Model, which began in July 2024, provides Medicare coverage for comprehensive dementia care, including:

  • Care coordination and management through interdisciplinary teams
  • Care Navigators to help families access services and resources
  • Up to $2,500 annually for respite services per eligible patient
  • Caregiver education and training programs

Additional FAQ's on Digital Home Care System

Yes. HITRUST CSF Certified security—same gold standard hospitals use. More secure than paper.

Extremely rare (99.9% uptime), but caregivers can work in offline mode if connectivity is temporarily lost. Care continues without interruption. Documentation syncs automatically when connection returns.

Caregivers document throughout their shift in real-time. Notes are typically finalized and visible in Family Room within minutes of the caregiver clocking out.

We can set up Family Room accounts for as many family members as you want—local siblings, children in other states, anyone you authorize. Everyone sees the same information. No limit on number of accounts.

Yes. Family Room includes secure document storage. Upload medical records, insurance cards, POLST forms, medication lists, doctor’s instructions, photos—anything important. All authorized family members can access these documents. No more searching for forms.

We update the digital care plan immediately, and all caregivers receive instant notification of changes. This is one of the biggest advantages over paper—updates reach everyone simultaneously, not gradually over days or weeks.

Absolutely. Family Room is a tool for families who want it, not a replacement for human connection. We’re always reachable by phone at (619) 736-4677. Many families use both—portal for quick updates, phone calls for detailed conversations.

We train every caregiver on the WellSky mobile app before their first shift. The app is intuitive—designed specifically for caregivers, not engineers. If someone can text and use GPS navigation, they can use our caregiver app. And we provide ongoing support.

Yes. The Family Room care calendar shows upcoming shifts with caregiver names and times. You’ll know exactly who’s coming and when. No more surprise caregiver switches.

Use the two-way messaging feature in Family Room. Send your message, and the caregiver receives an instant notification on their mobile app. They’ll see it and can respond or confirm receipt immediately.

Yes. All notes are searchable. Want to see every mention of “appetite” from the past month? Type it in the search bar and find all relevant notes instantly. No more flipping through pages of handwritten entries.

You can access the complete care history from the day Family Room access began. Review notes from last week, last month, or since care started. Historical data helps identify patterns over time.

Family members cannot delete caregiver documentation—that’s protected and maintained by All Heart for record-keeping purposes. You can delete your own uploaded documents, but we can often recover those if needed within a certain timeframe.

With your authorization, we can provide limited Family Room access to healthcare providers. This allows better coordination between home care and medical teams. You control exactly who has access and what they can see.

Family Room works both ways. You can access it through any web browser (Chrome, Safari, Firefox, Edge) on your computer, or download the mobile app for easier access on your phone or tablet. Your choice.

All authorized Family Room users see the same care information—we can’t create different access levels for different family members. However, you (as the primary contact) control who gets Family Room access in the first place. If family dynamics are challenging, you decide who receives login credentials.

The messaging system shows when messages are delivered and read. You’ll see confirmation that the caregiver received and opened your message. For critical information, you can also call our office to ensure the message was received.

Yes. You can print individual shift notes, date ranges, or specific types of documentation (like Change of Condition reports) directly from Family Room. Useful for doctor appointments or insurance purposes.

If your loved one transitions to hospice, hospital, or another care setting, we can maintain your Family Room access for a transition period so you have complete records. After care ends, we provide a final data export if requested, then access is closed according to your wishes and legal requirements.

Yes. Family Room is accessible from anywhere with internet connection. If you’re traveling abroad, you can still check on your loved one’s care. The system works globally.

Family Room doesn’t support selective information sharing—all authorized users see the same care documentation. For private family communications, you’d need to use personal email, phone, or text outside the Family Room system.

Change of Condition reports automatically alert you when caregivers document significant health changes. For custom alerts (like specific behaviors or situations), talk to our office—we may be able to add special flags to your loved one’s care plan that trigger notifications.

We typically set up Family Room access during your initial care planning meeting, before the first caregiver shift. You’ll have login credentials and a brief tutorial on how to use the portal. Most families are viewing their first shift notes within 24 hours of care beginning.

Additional Important Information

This comprehensive information ensures every caregiver provides consistent, personalized care from day one.

Tracking health changes that matter.

The Change of Condition form documents significant shifts in your loved one’s health—new symptoms, changes in mobility, behavioral differences, or improvements in their condition. This isn’t about minor day-to-day variations; it’s about meaningful changes that physicians, families, and caregivers need to know about.

Why have a separate form for this?

Instead of searching through weeks of caregiver narratives to find when symptoms started or conditions changed, this form puts all significant health changes in one easy-to-reference place. When doctors ask “when did the difficulty walking begin?” or family members want to understand the progression of a condition, you’ll have clear, dated documentation right at your fingertips.

What gets documented:

Each entry includes:

Why this form matters:

Early detection changes outcomes. When caregivers notice something different—increased confusion, difficulty walking, loss of appetite, or even positive improvements like better mobility—documenting it immediately allows for faster responses.

Your family stays informed about meaningful health changes. Physicians receive accurate updates during appointments instead of relying on memory. Incoming caregivers know exactly what’s changed and what new precautions or assistance your loved one needs.

One form. Complete health timeline. Better care.

Whether tracking a temporary change after a fall or documenting the progression of a chronic condition, the Change of Condition form creates a clear health timeline. This helps everyone—doctors, family members, and our San Diego caregiver team—understand how your loved one’s needs are evolving and respond appropriately.

Proactive monitoring isn’t just good practice. It’s essential senior care.

How the Caregiver Narrative works.

Each caregiver documents their shift using a simple timeline format that captures the essential details of your loved one’s day. This structured approach ensures consistency across all caregivers and makes information easy to find.

What we document in every narrative:

Narrative Format:

Each entry follows this structure:

Why this format works:

This timeline approach provides clear, chronological documentation that’s easy for incoming caregivers to read and understand. Instead of wondering what happened during the previous shift, they can see exactly what your loved one ate, how they felt, what activities they enjoyed, and any health changes observed.

One record. Every shift. Complete continuity.

Whether care is short-term, long-term, or evolving, the Caregiver Narrative ensures nothing gets missed and nothing gets repeated. Your family can review the journal at any time during visits, or we can share photos of recent narratives with long-distance family members who want to stay connected and informed.

Complete transparency and peace of mind, right when you need it.

Your loved one's complete care roadmap, now available digitally.

The All Heart Customized Care Plan is completed during your initial assessment and tailored to your loved one’s specific needs, preferences, mobility level, and safety requirements.

Now fully digital and accessible on every caregiver’s phone.

We’ve gone paperless. Your care plan is accessible through our digital platform—caregivers reference it anytime, anywhere. Updates happen in real-time, so when something changes, every caregiver sees it immediately.

What's included:

Care goals, emergency contacts, medical conditions, mental health & cognitive status, medications & supplements, mobility & transfers, personal care routines, meal prep & dietary needs, daily routines, activities & engagement, and home environment details.

One plan. Every caregiver. Consistent care.

This digital approach ensures every San Diego caregiver has the same accurate, up-to-date information from day one—promoting safety, continuity, and person-centered care.
